How did glaciers shape the lakes rivers soils and peat bogs of Newfoundland and Labrador?

During the Pleistocene Epoch, continental glaciation profoundly reshaped the landscape of Newfoundland and Labrador through extensive erosion and deposition.12

Lakes and Rivers

Glacial movement scoured the bedrock, creating countless basins and depressions that filled with water to form the province's numerous lakes and ponds. As glaciers retreated, meltwater carved wide valleys that are now occupied by major rivers. In many areas, the drainage systems were left interrupted or disorganized by glacial debris, which further contributed to the formation of complex networks of streams and lakes.1234

Soils and Peat Bogs

The glaciers stripped away preglacial soil and weathered debris, leaving behind a landscape often covered by a thin layer of glacial till or marine sediments exposed by postglacial uplift. While much of the bedrock was scraped bare, deeper surface deposits remain in some river watersheds, supporting forest growth and pockets of arable soil. The province's extensive peat bogs are a direct result of the interrupted drainage patterns and low-relief areas created by glacial scouring and the subsequent retreat of the ice sheets.124
